OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 653,894, dated July 17,1900.

Application filed April 18, 1899.

T0 at whom it may concern:

Be it known that I, WILLIAM H. WILDER, a citizen of the UnitedStates,residing at Gardner, Massachusetts, have invented certain new anduseful Improvements in Oil-Stoves, of which the following is aspecification.

My invention relates to that class of stoves now known to the trade asthe F automatic, adapted for the use of oil to burn a blue flame, theburner and reservoir having movement in relation to each other wherebyupon the movement of one or the other of said parts the burner ispartially or wholly filled or partially or wholly drained, the oil inthe reservoir being maintained at a constant level, and in the movementof the parts the burner is moved across this level to fill or empty thesame wholly or partially, or the level is raised or lowered bodily bythe adjustment of the oil-tank to vary this level in relation to theburner, all as fully set forth in various patents of the United Statesheretofore granted me.

The present invention includes many details of construction by which thecost of production has been decreased by the reduction of the number ofparts and the manner of arranging these parts, all as hereinafter fullydescribed.

In the accompanying drawings, Figure 1 is a front elevation of the stoveshown in cabinet form with the front door open. Fig. 2 is a verticalsection through the cabinet, showing the parts of one burner in sideelevation. Fig. 3 is an end elevation of the stove, showing thereservoir. Figs. 4 and 5 show details. Fig. 6 is a detail of anindicating-plate attached to the front door of the cabinet.

In the drawings I have shown the stove with a cabinet-frame instead ofthe skeleton frame commonly used, and this is advantageous, as itenables me to use a simpler construction of combustion-tubes and rendersunnecessary the external shields made necessary by the use of a skeletonframe. This cabinet-frame consists of a base A, composed of sheet metal,the front and end walls forming a rectangular frame with a door a at thefront. The top and bottom of this base are composed of sheet metalexactly alike, but

reversed in position, as shown in Fig. 2, and these plates 17 0 havetheir edges dished, as at cl, to fit over the upper and lower edges ofthe walls of the rectangular base A, while the parts are held togetherby wire rods 6, passing through the interior of the space of the base Aand provided on their lower ends with nuts f. Thus it will be seen thatthe parts can be readily put together and as readily detached.Seatedupon the base is the body B, this being slightly smaller than thebase and having rounded corners. The lower edge fits within thedepression of the plate I), this depression being formed by theupwardly-curved edges of the said plate, as shown at (Z. base and theshape of the upper body part B, with its rounded corners, presents avery attractive appearance and adds to the gen eral beauty of the stove.The body portion is perforated at the back to allow the admission ofsufficient air, as shown at g. 1

The burners C have a sliding connection with vertical extensions h of ahorizontal pipe line i, and thispipe at one end extends out side the endof the body portion and is held in place by astrap k. The end of thepipe is closed by a removable plug Z,- which may be taken out forcleaning the pipe should this be found necessary. At its opposite end astrap m clamps it to the top of the plate I). The ends of this strap arecontinued up wardly, as shown at n, and serve to support the oil-chambero, to the bottom of which the pipe 71 connects. Centrally of the pipe 4;two parts of a casting are clamped, having extensions p, and the bodypart B of the cabinet is held in place bya bail q, having its endssecured to the top plate D, and its loop engages one or the other of theprojections 19. By moving the loop of the bail laterally it isdisengaged from the projection 19, and this allows the part B to belifted clear of the base and to expose the burners for cleaning or otherpurposes. The top plate is provided with the usual openings providedwith gratesections r.

The reservoir I have improved by securing to it a handle of bail form,as shown at S, the ends of the bail having pivoted connection Therectangular shape of the with the side walls and secured thereto at agreater distance from the top of the reservoir than from the bottom.When the reservoir is in position within the oil-chamber o, the handleswings under the oil chamber, as shown in Fig. 1, not only out of theway, but serves also to prevent the accidental displacement of thereservoir. Then it is desired to remove the reservoir for fillingpurposes, the handle is lifted and with it the reservoir, whichimmediately turns upon the handle to an inverted position, with thefilling orifice uppermost, this action being caused by the position ofthe pivoted ends of the bail in relation to the bottom and top of thereservoir. This makes a very convenient form of reservoir. The oil-chamber 0 is strengthened by two brace-pieces 15, extending from sideto side of its inner walls.

The burners comprise an oil-holder in the shape of a cup 2 of a greaterdepth than width and of angular shape, and surmounting the cup is acombustion-chamber composed of perforated tubes for feeding air to theflame. The oil-holder is provided with an igniting medium, of asbestosor the like, though this is not essential. The burner is supplied withoil through a T-pipe, as shown in my former patent, the vertical part ofthe T having a sliding connection with the pipe h. The cup or oil-holderhas its lowest point where it connects with the cross-bar of the T-pipe,so as to be readily drained. The burner is moved upland down across amaintained oil-line to lower or raise the flame, as may be foundnecessary or desirable. The up-and-down movement is imparted to theburner by a very simple mechanism. The pipe 71. is provided with twogrooves 33, and a bracket 4:, made of two parts clamped together, fitsaround this pipe, with projections entering the grooves, and thus thebracket is not only properly seated, but accurately, and there is nodanger of slipping. A rack 5 of the shape shown fits around thehorizontal part of the T-pipe by means of a hook at its upper end, whilethe toothed part extends vertically. A lever 6 has a toothed inner end 7of segmental shape engaging the rack, this lever being pivoted on thebracket, as shown. On the side of the bracket I secure a casting of thepeculiar shape shown in Fig. 4. It is secured to the bracket adj ustablyand serves to limit the upward movement of the cup, to indicate theheight of the oil therein, and to tilt the combustion-chamber forigniting purposes, while at the same time this enables an unskilledperson to readily adjust the cup as to its extent of movement, so as tocause it to more readily flood in case the first adjustment was notperfect. This casting (shown at 7 is made symmetrical at each end, so asto be interchangeable and reversible, and thus capable of use on theright-hand side of one "casting and the left-hand side of the other.This casting 7 has a central slot which permits it to be secured to thebracket and to be adjusted thereon. It has a vertically-extendingpointer 8, which in the raising and lowering of the oil-holder indicatesthe depth of oil in the bowl. A projection 9 extends rearwardly .toimmediately in rear of the rack 5, having a turned-in end, and this isin the path of a stop 9 on the rack, thus limiting the upward movementof the burner. When the burner is lowered, the lower edge of the cuprests in the fork 10 of the casting 7, its movement being thus limiteddownward, and at the same time the end of the projection 9 strikes thebottom 9 of the combustion chamber (shown in dotted lines in Figs. 1 and2) and tilts the combustion-chamber on its seat on the oil-cup, thusexposing the front edge for igniting purposes.

The door of the part B preferably swings downward, being hinged at thebottom, and it has two vertical slots to allow the handles 6 of theoperating-levers to project, so that they can be operated from theoutside without opening the door. An indicator on the door shows wherethe pointer 11 on the han- (ile should be in the variouspositions,whether for lighting, high flame, low flame, or put out. Thehandles 6 of the operatinglevers are pivoted to the bracket 4, which hasswiveled connection with the pipe 71, and hence when it is desired tolift off the cabinet the door is swung on its hinges and the leversturned inwardly, as shown in Fig. 1, the bracket swiveling on the pipeh.
